Answer:16 Newton’s
Explanation:The equation for finding momentum is momentum= mass x velocity,so
2.0x8.0=16 Newton’s
It is the energy of the electrons I believe
Answer:
B. They show the pattern made by the magnetic field lines around the
magnets
Explanation:
Using iron fillings, the pattern of the magnetic field lines around a bar magnet can be known.
Magnetic field lines are the line of force around a bar magnet.
- These iron fillings will trace the pattern of the magnetic field around the magnet.
- The domains of the iron fillings begins to align and orient with that of the prevailing magnetic field around.
- Those areas with the strongest force will attract more fillings and those far away will attract lesser fillings.
There is no change in the weight of either
Air has no influence on the weight of an object unless the object is accelerating down through an air column. The air resistance to the free fall of the object may have an influence on its instantaneous weight of the object.
Explanation:
The weight of an object is influenced by the mass of the object and gravity. Gravity also has influence in a vacuum. Therefore the wooden and iron piece will weight the same in a vacuum as in the air.

Using the kinematics equation vf = vi + at we plug in all known values 15 = 5 + a*1 solving for a we get 10m/s^2
